CODEGEN-1703 Designated initializer plus struct hack hangs compiler Fixed C2000_16.6.0.STS, C2000_16.3.0.STS, C2000_16.9.0.LTS C2000_16.9.1.LTS Avoiding using string constants to initialize objects with flexible array members. Instead, use a brace-initialized array. For example: struct { int a; char b[]; } mystruct = {0, {'h', 'e', 'l', 'l', 'o'} }; Fixed a compiler hang caused by initializing flexible array members with string constants. struct {int a; char b[]; } mystruct = {0, "hello"} /* Would cause the compiler to hang and/or crash */
CODEGEN-1687 Assembler issues confusing diagnostic: Size is > 64 words, allocation will span page boundary Fixed C2000_16.6.0.STS, C2000_16.9.0.LTS C2000_16.9.1.LTS Compile source files without the --issue_remarks option. Blocking related diagnostics are longer be issued by the assembler when compiling C/C++ source files. However, these diagnostics will continue to be issued when compiling hand-coded assembly files. The diagnostics may be disabled by excluding --issue_remarks in the compiler options.
CODEGEN-1671 Arrays of Byte Peripherals or types aligned larger than their size should generate error Planned C2000_16.3.0.STS C2000_16.9.1.LTS Do not attempt to create an array of byte peripheral objects. The C language guarantees that the size of an array is equal to the size of each element times the number of elements. Because we double the alignment of byte peripheral data types but do not change the size, this does not hold true. There would be padding in the array, which is not allowed by the standard. Underneath the hood, we use the aligned GCC attribute to change the alignment for byte peripherals. On GCC, if you try to make an array of elements whose alignment is larger than its size (see example code below), you get the following error: "9:1: error: alignment of array elements is greater than element size" However, our parser doesn’t generate an error. Instead, it just reduces the alignment of the element size silently and makes an array. We need to generate an error and document that this is not allowed, both for byte peripherals and the aligned GCC attribute.
CODEGEN-1667 Assignment to 32-bit byte peripheral from 64-bit cast to 32-bit value causes internal error Fixed C2000_16.6.0.STS C2000_16.9.0.LTS Saving the cast value to a 32-bit temp and then assigning to the 32-bit byte peripheral will work at optimization settings of 0 and off. If a 64-bit value is cast to a 32-bit value and then assigned to a 32-bit byte peripheral type, an internal error occurs.
CODEGEN-1662 Optimizer incorrectly detects __fmin and __fmax idioms Fixed C2000_16.6.0.STS, C2000_16.3.0.STS C2000_16.9.1.LTS If you want floating-point absolute value, use fabs. However, there are other ways this bug could be triggered that have no practical workaround other than to use -Ooff
CODEGEN-1640 MISRA 19.1 misreported: #include statements should only be preceded by other preprocessor directives Planned C2000_16.6.0.STS, C2000_16.3.0.STS, C2000_16.9.0.LTS C2000_16.9.1.LTS No practical workaround
CODEGEN-1634 MISRA 7.1 misreported: octal tokens in token paste Planned C2000_16.6.0.STS, C2000_16.3.0.STS, C2000_16.9.0.LTS C2000_16.9.1.LTS No practical workaround
CODEGEN-1632 MISRA 15.2 misreported: switch clause unconditional break Planned C2000_16.6.0.STS, C2000_16.3.0.STS, C2000_16.9.0.LTS C2000_16.9.1.LTS Put an explicit break at the end of the compound statement
CODEGEN-1517 #pragma FUNCTION_OPTIONS meaningless unless at least -o0 is used Planned C2000_16.9.0.LTS
CODEGEN-1510 Assembler incorrectly issues warning on large constant used with MOVI32 instruction Fixed C2000_16.9.0.LTS C2000_16.9.0.LTS
CODEGEN-1420 Compiler mistakenly overwrites upper 32-bits to 0 by using MOVZ instruction to compute var32 |= 0x20 Fixed C2000_16.9.0.LTS C2000_16.9.1.LTS Fixed an issue where the compiler would issue a MOVZ instruction that zeroes the upper bits of an XAR register when those upper bits are needed for a future instruction.
CODEGEN-1333 Structure assignment causes compiler to fail with INTERNAL ERROR: Decomposition error Fixed C2000_16.6.0.STS C2000_16.9.0.LTS Replace struct assignments involving packed structures with a memcpy() call to copy the contents of the RHS of the struct assign to the LHS.
SDSCM00040386 Remove -olength option from hex utility's help summary and Users Guides Fixed C2000_16.9.0.LTS C2000_16.9.0.LTS
SDSCM00052603 Linker runs auto RTS even when errors have occurred Fixed C2000_16.3.0.STS None.
